I am working on my Ph.D. of Computer Science at Purdue University.

I was a former Ph.D. student at the Ohio State University where I received my M.S. from the Department of Computer Science and Engineering.

I received my B.S. in Computer Science from Cornell University.

My research focus is in the areas of graph learning and algorithms, topological data analysis, and high performance computing. My advisor is Dr. Tamal Dey

I am currently interning at Argonne National Laboratory in the Data Science and Learning Division.
